Being designated a NPL site require n Investigatio a a subsequens d an r tfo n remediatio f potentiao n l chemical contamination that may be present on site. Through Its prime contractoS CorporationNU e th r Zon fo r, Regioe I e ,th I officII n d stafan e f fo the USEPA has Investigated the site and has developed a remediation plan which It Is prepared to Implement. This remedial alternative 1s detailed In the Record-of-Decisio ne site th (ROD . r )fo Remediatio n currently proposeA EP y b d would Involve excavation and removal of drums, drum fragments and waste, applying e sitecoveth s o ventingga t mucf ,ro h , o largfillintw ef o g depressions, cleanout of two ponds, backfilling and revegetatlon. Post-closure care would Include ground water and surface water monitoring and topsolllng/revegetatlon.

Durin 1960'se th g Cite ,th y of Scranton used the open pits as a sanitary landfill, effectively reclaiming the site and grading It to an approximate 5% grade, sloping northwest to southeast.

These drums were subsequently removed by the USEPA during a remedial cleanup. In October of 1985, following a brush fire at the site.
